Britons are being advised to take precautions while traveling abroad following the revelation of over 1,000 cases of travel-related illnesses reported this year. Among the illnesses recorded are malaria, dengue fever, and Zika virus.
Preventive measures such as vaccination, taking malaria prophylaxis, and maintaining good hygiene practices can significantly reduce the risk of falling ill while traveling. The latest data released by Travel Health Pro, a division of UK Health Security Agency (UKHSA), sheds light on the current situation.
Between January and June 2026, in England, Wales, and Northern Ireland (EWNI), the Zika virus, primarily transmitted by mosquitoes in regions like South and Central America, the Caribbean, Africa, and Asia, has led to eight reported cases. Notably, Indonesia accounted for the highest number of reported Zika virus cases this year compared to previous years.
Chikungunya, another mosquito-borne infection characterized by sudden fever and joint pain, saw 59 reported cases, with Sri Lanka being the most frequently visited country among those affected.
Malaria, a severe mosquito-borne disease, resulted in 557 cases reported in EWNI from January to May 2026. Additionally, enteric fever cases, including typhoid and paratyphoid fever, totaled 287 cases. Dengue fever, a mosquito-transmitted infection, led to 137 reported cases in England, with South-East Asia and South Asia being common regions of exposure.
Dr. Hilary Kirkbride, a consultant epidemiologist and head of travel health at UKHSA, emphasized the importance of preparation and planning for safe travel during the summer season. Travelers are advised to visit the TravelHealthPro website for updated health advice specific to their destination, including necessary vaccinations and medications like antimalarials. Protection against mosquito-borne diseases can be enhanced by using insect repellent, covering exposed skin, and sleeping under treated bed nets if needed. Precautions against food and waterborne infections like enteric fever are also crucial.
Travelers are reminded that even if they have visited a country before, they may not have the same immunity as local residents, necessitating consistent precautions. Special care should be taken by pregnant individuals or those planning to conceive, who are advised to consult with healthcare professionals before traveling.
